Subsurface imaging with low frequency SAR: Field validation in Egypt using a ground-penetrating radar

Abstract

We study the capabilities of low frequency radar systems to sound the subsurface in arid countries. This approach is based on the coupling between two complementary radar techniques: the spaceborne Synthetic Aperture Radar (SAR) used in L-band (1.2 GHz) for imaging large scale subsurface structures, and the Ground-Penetrating Radar (GPR) used between 500 and 900 MHz for sounding the soils at local scale from the surface down to several meters. We report the preliminary results obtained in the Southern Egyptian Desert. The qualitative comparison between L-band SAR and GPR sections shows that penetration effects occur in many places, revealing rich subsurface structures. Preliminary results are commented and future quantitative analysis of these data should lead us to understand the physical processes acting in such typical arid context.
